Scientific study of interactions among organisms and between organisms and their enviroment.

Part of Earth in which life exists including land, water, and air or atomsphere.

Group of similar organisms that can breed and produce fertile offspring.

group of individuals of the same species that live in the same area.

Assemblage of different populations that live together in a defined area.

Collection of all the organisms that live in a particular place, together with their nonliving environment.

Organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer.

Organism that obtains energy from the foods it consumes; also called a consumer.

Network of complex interactions formed by the feeding relationships among the various organisms in the ecosystem.

Step in a food chain or a food web.

Total amount of living tissue within a given trophic level.

Process in which elements, chemical compunds, and other forms of matter are are passed from one organism to another and from one part of the biosphere to another.

Largest number of individuals of a population that a given environment can support.

Scientific study of human populations

Demographic Transition

change in a population from high birth and death rates to low birth and death rates
